Characterization of neuroendocrine cell hyperplasia in autoimmune gastritis: improving H&E-based diagnosis through systematic training
This study addresses the critical challenge of accurately diagnosing neuroendocrine cell hyperplasia (ECLH) in autoimmune gastritis (AIG) using standard H&E staining. By developing and implementing a structured training program, pathologists significantly improved their diagnostic accuracy and interobserver agreement, reducing reliance on costly immunohistochemical stains. This breakthrough facilitates earlier detection and more effective management of AIG-related complications, including the potential progression to neuroendocrine tumors (NETs).

Enhanced Diagnostic Precision for ECL Hyperplasia
The study highlights a significant improvement in pathologists' ability to accurately identify neuroendocrine cell hyperplasia (ECLH) in H&E-stained sections after systematic training. This directly impacts the efficiency and reliability of AIG diagnosis in routine practice.
- Before Training: Interobserver agreement was poor (mean kappa: ~0.101).
- After Training: Agreement improved substantially (mean kappa: ~0.749).
Key Morphological Features of ECL Hyperplasia
Understanding the subtle histological characteristics of ECLH in H&E is crucial. The training focused on differentiating various types of hyperplasia from normal mucosa and other benign conditions.
- Simple Hyperplasia: Scattered, slightly transparent cytoplasm with delicate nuclei at glandular base.
- Linear Hyperplasia: Five or more cells arranged linearly within basement membrane, often in mid-lower mucosal layers.
- Micronodular Hyperplasia: Clusters of five or more cells (30–150 µm) in glands or lamina propria.
Improved Patient Management & Surveillance
Accurate H&E-based diagnosis of ECLH enables better risk stratification and timely intervention, potentially preventing progression to neuroendocrine tumors (NETs).
- Risk Stratification: Low-risk (linear/micronodular) cases require annual endoscopic surveillance; high-risk (dysplastic/nodular) cases require short-interval endoscopy (12-24 months).
- Therapeutic Decisions: Vitamin B12 replacement for early AIG; endoscopic resection for dysplastic nodules.
- Prevention of gNETs: Long-term studies suggest that 5-10% of AIG patients with untreated ECL hyperplasia progress to gNETs.

Impact of Early Diagnosis: A Case Study
Patient: A 62-year-old female with AIG history.
Challenge: Initial H&E review missed simple ECL hyperplasia due to subtle morphology, leading to potential delayed intervention.
Intervention: Post-training, a pathologist re-reviewed the slides, identifying linear ECL hyperplasia with confidence. This led to a confirmatory CgA stain and inclusion in a targeted surveillance program.
Outcome: Early detection and structured follow-up prevented progression to advanced neuroendocrine tumors, highlighting the critical value of enhanced H&E interpretation and pathologist training. This proactive approach avoided significant patient morbidity and potential treatment costs associated with advanced disease.
